摘 要 ：利用流式细胞光度术测定了苹果１２个二倍体，５个三倍体细胞ＤＮＡ含量。结果表明：二倍体细胞核ＤＮＡ含量平均为２．２７ｐｇ，三倍体细胞核ＤＮＡ含量平均为３．１３ｐｇ。

Abstract:Content of nuclear DNA for apple cultivars including 12 diploid and 5 triploid was measured by flow cytometry.The average nuclear DNA content of diploid cultivars was 2.27 pg and that of triploid cultivars was 3.13 pg,which indicated that variation of nuc
